sHUTTsR-BOLT.

PECIFICATION forming part of .Letters Patent No. 315,681, dated April 14, 1885.

Application filed January 21, l'. (Xo model.)

To @ZZ whom it may con/cern.:

Be it known that I, JOHN Voir HOLLEN, of Charleston., in the county of Charleston and State of South Carolina, have invented a new and Improved Shutter-Bolt, of which the following is a full, clear, and exact description.

illy invention relates to fastenings and bolts for securing bars over closed window shutters or blinds, and for other purposes.

The invention consists in providing a collar near the inner conically-headed end of the extensible catch of the bolt, said collar serving as a bearing for the inner end of the bolt in the hole made in the Window-frame or wall or other object to receive the bolt-catch.

The invention consists also in particular constructions and combinations of parts of the shutter bolt and fastenings, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, Aforming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a view of a pair of shutters hung to a window and secured by an outside bar fastened at one end by my improved shutter bolt. Fig. 2 is an enlarged vertical sectional elevation through the window frame orrcasing, the shutter-bar, and the bolt, and taken on the line x Fig. l. Fig. 3 is a side elevation of the extensible catch of the bolt, and Fig. et is a front view of the latch-bar and plate of the bolt.

The letter A indicates the frame or wall on which the shutters B are hinged or set up in any way to cover a window or store-front, and C is the shutter-bar, which, as shown, is pivoted at c at one end to one side of the frame or wall A, and is secured over the closed shutters by Vmy improved shutter-bolt.

The shutter-bolt herein shown and described is similar in most respects to the bolt nientioned in my application for a United States patent, filed May 2S, 1884, and consists, mainly, of an extensible catch, D, formed of a hollow bar or tube, D', having a screw-tapped hole in its forward end, into which the externallythreaded part D2 of the catch ts, so it may be turned out or in to lengthen the bolt, a setscrew, d, being provided in the part D by which to lock the two parts D D2 together at any desired adjustment. The bach end of the part D has a collar or shoulder, d', which comes against the face of the shutter-bar C, and the forward end of the part D2 has a conical head, F, forming a shoulder, f, behind which the sliding latch-bar G, which is fitted to the face-plate H, may drop to lock the extensible bolt-latch D in place, said face-plate H being secured by screws 71. or otherwise to the inside face of the frame or wall A.

The present improvement consists in forining a collar, l, on the part D2 of the bolt behind the conical head F ashort distance-say about three-quarters of an inch, more or less. The object of the collar I, which is about of the same diameter as the part D of the bolt, is to steady the forward end part, D2, of the bolt by bearing against the walls of the opening J, made through the frame or wall A to receive the bolt, and thereby prevent bending of the inner end, D?, of the bolt, so it may remain true and straight to allow it to be run in or out of the threaded or nut portion 'of the part D', as will readily be understood.

Then the bolt as last described is used with window shutters or blinds to hold them open, as illustrated in a general way in the aforesaid application for a patent, the collar I will serve by acting behind the catch G to prevent noisy shaking of the open blind on its hinges.

In fastening the shutters B by the bar C and the shutter-bolt, the bar will be swung over the shutters on its pivot c until its op posite end hole, c', coincides with the hole J of the frame or wall at the opposite side of the window, as in Fig. l, and the bolt-catch D, having been adjusted to proper length, will be passed through the holes c J, and its conical head F will strike the latch-bar G and lift and pass it, when the latchbar will drop behind the shoulderf, as in Fig. 2, and the fast ening will be complete, and the bolt D cannot be removed from the outside, so that the shutters will be securely barred. l

To remove the bar C for opening or taking down the shutters, it only is necessary to lift the latch-bar Cr above the shoulder f, when the bolt D may be withdrawn, so the bar may hang down from its end pivot, c, at one side of the window; or, if desired, a bolt-catch and latch-bar, D G, may-be tted to the windowframe or wall, so as to secure the bar G thereby at both ends to allow it to be entirely removed frorn the window-frame when the shutters are to be opened or taken down.

A metal tube may be fitted in the wind0wframe or wall A, through which the shutterbolt catch D may pass, if desired.

Having thus described my invention', what I claim as new, and desire to secure byLetters Patent, is-

1'. The combination, in a shutter-fastening, and with the barO, laid over the window-shutters, of an extensible catch, D, formed of two parts, D D2,serewed to each other, said part D having a head or collar, d', and the part D2 having a conical head, F, and a sliding latehbar, G, fitted to the window-frame or wall, and adapted to engage the catch-bar behind its head F, substantially as herein set forth.

2. As animproved article of manufacture, a eateh for a shutter-bolt, made with a tubular screw-threaded part, D', having a head or collar, d', and a screw-threaded and eonieallyheaded part, D2, adapted to be adjusted on the part D to vary the length of the eateh, and said part D2 having the collar I, substantially as herein set forth.

3. The combination, with the parts D D2 of the shutter-bolt, screwed to each other and constructed with the collar or head d, conical head F, and collar I, as specified, of the setscrew d, substantially as herein set forth.
